Just came across this deal while searching for a cheap unlimited ADSL2+ option. Seems to be a $10 discount from the normal $39.90 p/m unlimited option. All it says is "Limited Time Offer" with no expiry that I could see. Obviously Dodo has its problems, but $29.90 p/m seems like a pretty good deal for ADSL2+ with unlimited downloads. I've used them in the past without too many issues, but I know others have complained about poor speeds at peak times at certain exchanges, poor customer service, etc.
Note: this price applies to metro connections only
UPDATE: Found this TV Ad advertising the deal with expiry date of 30 June —> https://www.youtube.com/watch?v=vnUkGrOEVOw
